对我国当代图书出版数学模型的评价与完善

The Appraisal and Improvement on the Mathematical Model of Contemporary Book Publishing in China

对李华在《对〈我国当代图书出版数学模型的研究〉一文的思考》中建立的线性回归模型进行了统计检验、预测精度方面的评价，指出兰凌在《关于我国当代图书出版数学模型的建议》中对该模型的批评意见是不正确的，修正了该模型中存在的自相关问题。

Abstract Based on statistical tests and prediction precision analysis of the linear regression model,which was formulated in“Some thought on the study of mathematical model of contemporary book publishing in China”(Li Hua), this paper indicates that the criticism to the model, which was given in “Suggestions on the mathematical model of contemporary book publishing in China”(Lan Ling), is incorrect, then reformulates the model to solve the autocorrelation problem and cuts down the prediction error.
